Psalms 39:1

1. I said, I will take heed to my ways. David explains and illustrates the greatness of his grief by this circumstance, that, contrary to his inclination and resolution, he broke forth into the severest complaints. The meaning substantially is, that although he had subdued his heart to patience, and resolved to keep silence, yet the violence of his grief was such that it forced him to break his resolution, and extorted from him, if we might so speak, expressions which indicate that he had given way to an undue degree of sorrow. The expression, I said, it is well known, does not always mean what is expressed in words, but is often used to denote the purpose of the heart, and, therefore, the words in heart are sometimes added. David, therefore, means not that he boasted of his fortitude and constancy, and made a display of them before men, but that before God he was, by continued meditation, well fortified and prepared to endure patiently the temptations by which he was now assailed. We ought to mark particularly the carefulness by which he was distinguished. It was not without cause that he was so much intent on exercising watchfulness over himself. He did so because he was conscious of his own weakness, and also well knew the manifold devices of Satan. He, therefore, looked on the right hand and on the left, and kept watch on all sides, lest temptation stealing upon him unawares from any quarter might reach even to his heart. Access to it, then, had been impossible, since it was shut up on every side, if the extreme severity of his grief had not overpowered him, and broken his resolution. When he says, I will keep my mouth with a muzzle, that I sin not with my tongue, it is not to be understood as if he could with difficulty restrain and conceal his grief, (for it is mere pretense for a man to show by the countenance and speech the appearance of meekness when the heart still swells with pride;) but as there is nothing more slippery or loose than the tongue, David declares that he had endeavored so carefully to bridle his affections, that not so much as one word should escape from his lips which might betray the least impatience. And that man must indeed be endued with singular fortitude who unfeignedly and deliberately restrains his tongue, which is so liable to fall into error. As to what follows, while the wicked standeth before me, it is generally understood, as if David had concealed his grief, lest he should give occasion of blasphemy to the wicked, who, as soon as they see the children of God fail under the weight of their afflictions, insolently break forth into derision against them, which amounts to a contempt of God himself. But it appears to me that by the term standeth, David meant to express something more, — that even while he saw the wicked bearing rule, exercising authority, and exalted to honor, he resolved not to speak a single word, but to bear patiently the poverty and indignity which otherwise grieve and torment not a little even good men. Accordingly, he says not merely that when he was in the presence of the wicked he restrained himself, lest he should be subjected to their scorn, but that even while the worst of men prospered, and, proud of their high rank, despised others, he was fully determined in his own mind not to be troubled at it. By this he very plainly shows that he was so beset with wicked men, ever ready for mischief, that he could not freely heave a sigh which was not made the subject of ridicule and scorn. Since, then, it was so hard a task for David to restrain his tongue, lest he should sin by giving way to complaints, let us learn from his example, whenever troubles molest us, to strive earnestly to moderate our affections, that no impious expression of dissatisfaction against God may slip from us.
